I created 12 histograms for 12 frames and I need to get the local minimums of these histograms.

hello
maybe this
the local minima are the red diamonds
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/972460/image.png)
x = randn(1000,1);
h = histogram(x);
Values = h.Values;
BinCounts = h.BinCounts;
BinEdges = h.BinEdges;
BinWidth = h.BinWidth;
centers = BinEdges(2:end) - BinWidth/2;
% find min values
ind = islocalmin(Values);
hold on
plot(centers(ind),Values(ind),'dr');
hold off

So the "why you need it" is a closely held secret? You basically said you need it because you need it. Let me challenge you and say that you don't need it to do whatever mysterious thing you're attempting to do. Prove me wrong.
